CMA TAX-EXEMPT FUND, MARCH 31, 2004 A Letter From the President Dear Shareholder Index returns during the most recent six-month and 12-month reporting periods indicate that fixed income markets - both taxable and tax-exempt - continued to reward those investors who were willing to accept greater risk. The high yield market, as measured by the Credit Suisse First Boston High Yield Index, provided a six-month return of +8.65% and a 12-month return of +22.86% as of March 31, 2004. By comparison, the Lehman Brothers Aggregate Bond Index returned +2.98% and +5.40% and the Lehman Brothers Municipal Bond Index returned +3.12% and +5.86% for the six-month and 12-month periods ended March 31, 2004, respectively. As of March month-end, the Federal Reserve Board maintained its accommodative policy stance, pledging "patience" in raising interest rates. As a result, short-term interest rates remained at historic lows and kept the short end of the yield curve relatively flat, making it increasingly difficult to find attractive income opportunities. Market watchers continue to monitor the economic data and Federal Reserve Board language for indications of interest rate direction. Having said that, if the economy continues to grow at its recent pace, many believe it is just a matter of time before interest rates move upward. Equity markets, in the meantime, continued to provide attractive returns. For the six-month and 12-month periods ended March 31, 2004, the Standard & Poor's 500 Index returned +14.08% and +35.12%, respectively. Much of the boost came from improving economic conditions throughout the past year. Significant fiscal and monetary stimulus, including the low interest rates and tax cuts, has opened the door to consumer spending, capital spending, increases in exports and long-awaited job growth. As expected, these positive developments have led the way to improvements in corporate earnings - a positive for stock markets. The events and efforts of the past year leave us with a much stronger economy today. With all of this in mind, we believe it is time for investors to consider what can go right in 2004. We encourage you to revisit your portfolio and your asset allocation strategy to ensure you are well positioned to take advantage of the opportunities that lie ahead. Your financial advisor can help you develop a strategy designed to perform through all types of market and economic cycles. We thank you for trusting Merrill Lynch Investment Managers with your investment assets, and we look forward to serving you in the months and years ahead. Sincerely, (Terry K. Glenn) Terry K. Glenn President and Trustee CMA TAX-EXEMPT FUND, MARCH 31, 2004 A Discussion With Your Fund's Portfolio Manager We sought to maintain the Fund's stake in fixed rate municipal notes while still taking advantage of favorable price swings in shorter- term variable rate demand notes when available. How did the Fund perform during the fiscal year in light of the existing market conditions? For the 12-month period ended March 31, 2004, CMA Tax-Exempt Money Fund paid shareholders a net annualized yield of .54%.* As of March 31, 2004, the Fund's seven-day yield was .52%. Throughout the period, an accommodative Federal Reserve Board continued to maintain interest rates near historically low levels. The last in a series of interest rate cuts came in June 2003, as the Federal Reserve Board looked to stimulate economic growth and ward off the potential for deflation. Although economic growth began to accelerate later in the year, concerns over weak job growth persisted in the market. Investors tried to anticipate when the Federal Reserve Board would restore interest rates to more neutral levels. The constant interest rate analysis translated into widespread volatility, which created opportunities in the fixed income markets. Within this framework, our strategy has been to overweight fixed rate notes and maintain a portfolio maturity slightly longer than the average of our peer group. The yield pickup achieved from the maturity extension into fixed rate notes was beneficial throughout the period and contributed positively to the Fund's performance. What changes were made to the portfolio during the period? Our overall strategy remained relatively stable over the past 12 months. That is, we continued to emphasize fixed rate notes - which have maturities of up to 13 months - over variable rate paper because of their longer maturity dates. With interest rates generally declining and expected to remain low for some time, fixed rate notes offered somewhat higher yields and added to the Fund's performance. For example, the average yield on one-year notes, as measured by the Bond Buyer One-Year Note Index, was 1.08% during the 12-month period. By contrast, the average yield on seven-day variable rate paper, as measured by the BMA Municipal Swap Index, was 1.00% for the same period. *Based on a constant investment throughout the period, with dividends compounded daily, and reflecting a net return to the investor after all expenses. During times of low issuance, we tended to use tax-exempt commercial paper to extend the portfolio's maturity and diversify our exposure to include a variety of spots on the short-term tax-exempt yield curve. In contrast, during periods of exceptionally heavy issuance or following a market sell-off, we looked for opportunities to lock in attractive yields for extended periods of time. One of the biggest management challenges faced during the period occurred between June and September 2003, when higher-yielding notes in the Fund matured and had to be replaced in a lower interest rate environment. We were able to take advantage of heavy supply in Texas and California and found suitable replacement securities to maintain the Fund's attractive yield. How would you characterize the portfolio's position at the close of the period? We believe the portfolio is positioned to continue its recent strong performance. We do anticipate a period of redemption activity surrounding income tax season. During this time, interest rates on short-term securities are likely to spike, making fixed rate notes appear unattractive on a relative basis. This should be a temporary phenomenon, and we would expect the yield curve to resume its normal slope by late May. A large amount of the portfolio's notes will mature in June, most notably a significant position in California revenue anticipation warrants. This could create unusually strong demand in mid-June as investors look to replace the maturing notes, possibly causing yields on short-term tax-exempt securities to fall. We will watch this situation closely as we look for attractive opportunities to reinvest the proceeds from the Fund's maturing notes. Finally, we will continue to monitor changes in the economic climate - including the potential for interest rate increases - which would cause us to adopt a more defensive strategy in managing the portfolio.

See Notes to Financial Statements. CMA TAX-EXEMPT FUND, MARCH 31, 2004 Notes to Financial Statements CMA Tax-Exempt Fund 1. Significant Accounting Policies: CMA Tax-Exempt Fund (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a no load, diversified, open-end management investment company. The Fund seeks to achieve its investment objective by investing all of its assets in the Master Tax-Exempt Trust (the "Trust"), which has the same investment objective as the Fund. The value of the Fund's investment in the Trust reflects the Fund's proportionate interest in the net assets of the Trust. The performance of the Fund is directly affected by the performance of the Trust. The financial statements of the Trust, including the Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The Fund's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. The percentage of the Trust owned by the Fund at March 31, 2004 was approximately 92.9%. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--The Fund records its investment in the Trust at fair value. Valuation of securities held by the Trust is discussed in Note 1a of the Trust's Notes to Financial Statements, which are included elsewhere in this report. (b) Investment income and expenses--The Fund records daily its proportionate share of the Trust's income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own expenses. (c) Income taxes--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no Federal income tax provision is required. (d) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. (e) Dividends and distributions to shareholders--The Fund declares dividends daily and reinvests daily such dividends (net of non- resident alien tax and backup withholding tax withheld) in additional fund shares at net asset value. Dividends and distributions are declared from the total of net investment income and net realized gain or loss on investments. (f) Investment transactions--Investment transactions are accounted for on a trade date basis. (g) Reclassification--Accounting principles generally accepted in the United States of America require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, the current year's permanent book/tax difference of $54,245 has been reclassified between paid-in capital in excess of par and undistributed investment income. This reclassification has no effect on net assets or net asset value per share. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Administration Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), a wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. The Fund pays a monthly fee at an annual rate of .25% of the Fund's average daily net assets for the performance of administrative services (other than investment advice and related portfolio activities) necessary for the operation of the Fund. The Fund has adopted a Distribution and Shareholder Servicing Plan in compliance with Rule 12b-1 under the Investment Company Act of 1940, pursuant to which Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of ML & Co., receives a distribution fee from the Fund. The fee is accrued daily and paid monthly at the annual rate of .125% of average daily net assets of the Fund for shareholders who maintain their accounts through MLPF&S. The distribution fee is to compensate MLPF&S financial advisors and other directly involved branch office personnel for selling shares of the Fund and for providing direct personal services to shareholders. The distribution fee is not compensation for the administrative and operational services rendered to the Fund by MLPF&S in processing share orders and administering shareholder accounts. CMA TAX-EXEMPT FUND, MARCH 31, 2004 Notes to Financial Statements (concluded) CMA Tax-Exempt Fund Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co., is the Fund's transfer agent. Certain officers and/or trustees of the Fund are officers and/or directors of FAM, PSI, FDS, and/or ML & Co. 3. Transactions in Shares of Beneficial Interest: The number of shares sold, reinvested and redeemed during the periods corresponds to the amounts included in the Statements of Changes in Net Assets for net proceeds from sale of shares, value of shares reinvested and cost of shares redeemed, respectively, since shares are recorded at $1.00 per share. In addition, on August 18, 2003, $741,257,384 was transferred to WCMA Tax-Exempt Fund as planned, following the formation of that Fund. 4. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended March 31, 2004 and March 31, 2003 was as follows: 3/31/2004 3/31/2003 Distributions paid from: Tax-exempt income $ 54,690,122 $ 97,179,406 ------------- ------------- Total distributions $ 54,690,122 $ 97,179,406 ============= ============= As of March 31, 2004, there were no significant differences between book and tax components of net assets. 5. Capital Loss Carryforward: On March 31, 2004, the Fund had a net capital loss carryforward of $436,599, of which $72,081 expires in 2008, $144,287 expires in 2011 and $220,231 expires in 2012.

See Notes to Financial Statements. CMA TAX-EXEMPT FUND, MARCH 31, 2004 Notes to Financial Statements Master Tax-Exempt Trust 1. Significant Accounting Policies: Master Tax-Exempt Trust (the "Trust") is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interest in the Trust, subject to certain limitations. The Trust's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. The following is a summary of significant accounting policies followed by the Trust. (a) Valuation of investments--Investments are valued at amortized cost, which approximates market value. For the purpose of valuation, the maturity of a variable rate demand instrument is deemed to be the demand notice payment period. In the case of a floating rate instrument, the remaining maturity is the next coupon date on which the interest rate is to be adjusted. (b) Income taxes--The Trust is classified as a partnership for Federal income tax purposes. As such, each investor in the Trust is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Trust. Therefore, no Federal income tax provision is required. It is intended that the Trust's assets will be managed so an investor in the Trust can satisfy the requirements of Subchapter M of the Internal Revenue Code. (c) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Interest income (including amortization of premium and discount) is recognized on the accrual basis. 2. Investment Advisory Agreement and Transactions with Affiliates: The Trust has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for the management of the Trust's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Trust. For such services, the Trust pays a monthly fee based upon the average daily value of the Trust's net assets at the following annual rates: .25% of the Trust's average daily net assets not exceeding $500 million; ..175% of the average daily net assets in excess of $500 million but not exceeding $1 billion; and .125% of the average daily net assets in excess of $1 billion. For the year ended March 31, 2004, the Trust reimbursed FAM $203,561 for certain accounting services. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, and/or ML & Co. CMA TAX-EXEMPT FUND, MARCH 31, 2004 Independent Auditors' Report Master Tax-Exempt Trust To the Investors and Board of Trustees of Master Tax-Exempt Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Master Tax-Exempt Trust as of March 31, 2004, and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for the year then ended and for the period February 13, 2003 (commencement of operations) through March 31, 2003. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 31, 2004, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Master Tax-Exempt Trust as of March 31, 2004, the results of its operations for the year then ended, the changes in its net assets, and its financial highlights for the year then ended and for the period February 13, 2003 through March 31, 2003, in conformity with accounting principles generally accepted in the United States of America.

Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for the project as a whole. Any proposed services exceeding the pre- approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre- approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting.
